title: Red cell distribution width and hypertensive response to exercise in patients with type 2 diabetes mellitus.
abstract: OBJECTIVE
  There is no study about hypertensive response to exercise (HRE), which is a marker of unborn hypertension (HT), and red cell distribution width (RDW) association, in diabetic normotensive patients. So, we aimed to investigate any correlation among RDW and HRE in normotensive type 2 diabetic patients.
  
  
  METHODS
  Consecutive type 2 diabetic patients without history of HT and with normal blood pressure (BP) on ambulatory BP monitoring were included to the study. We divided the patients into two groups depending on their peak systolic BP on exercise; HRE (Group 1) or normal response to exercise (Group 2).
  
  
  RESULTS
  Data of 75 diabetic patients (51.9 ± 9.7) were analyzed (31 male (48%)). Their mean RDW was 13.11 ± 0.46. Patients with HRE were significantly older than patients without HRE. Smoking was more frequent in Group 2. Gender distribution and body mass index were similar between the groups. Else hemoglobin, hematocrit, red blood cell count and RDW values were not significantly different. Office systolic BP and diastolic BP, daytime and 24-h systolic BP were significantly higher in Group 1 but heart rate was similar between the groups.
  
  
  CONCLUSIONS
  This study revealed that RDW do not differ between diabetic normotensive patients with HRE or not.
